XMPP

Mickaël Rémond from the recent Portland Jabber Meeting...

At the end of the day, we were almost able to federate on a secure network, but there is still some interop work to be done to make this work flawlessly. That's why we all commited to make this secure federation of IM network running on different code base work in a close future. I agree with Jacques Belissent that building an open, highly secure xmpp federation based on a pretty diverse set of implementations is a very exciting and close prospect...

I deeply feel that we are only at the beginning. Something really big is now happening around XMPP (eXtensible Presence and Messaging Protocol).
